A demo that supports retriggers is a slot game that treats its free spins round as open-ended rather than fixed. Most slots set a defined spin count for the bonus and run it to completion. A retriggerable round leaves that count negotiable. Scatters landing during the bonus add more spins to whatever remains, extending the session inside the bonus rather than closing it out. That design choice signals something about how the developer weighted the bonus relative to regular play.
The retrigger works by keeping the scatter symbol active during the free spins round. When the qualifying number of scatters lands again, additional spins are added to the remaining count rather than launching a separate bonus instance. The number of spins awarded per retrigger usually matches or approximates the original trigger amount, though some titles award a fixed smaller number. Many games cap the total spins available through retriggers to prevent the round from extending indefinitely, and the cap is always specified in the paytable.
No. A retrigger adds spins to the existing round rather than resetting it. Any accumulated features, such as sticky wilds, growing multipliers, or collected values, carry over into the extended spins rather than being cleared. This distinction matters considerably in games where the bonus builds state across multiple spins, since a retrigger maintains that progress rather than wiping it.
No, and the absence of retriggers is a deliberate design decision as often as it is an oversight. Some games remove retrigger capability in exchange for a more powerful base bonus setup, or apply conditions that make scatters unable to land during the free spins phase at all. Others allow retriggers freely with no cap. Checking the paytable before a demo session will confirm whether retriggers are possible and, if so, whether any ceiling applies.
